1. Configuration FIG. 1 is a diagram showing an outline of a vital data providing system 1 according to an embodiment. The vital data providing system 1 is a system for providing vital data. Vital data refers to data that can be obtained from the human body, such as blood pressure, heartbeat, body temperature, oxygen saturation (blood oxygen), body weight, blood sugar, urine sugar, uric acid (in blood or urine), oxalic acid, and specific gravity. , Protein, urobilinogen (liver system), pH, serum iron, inflammatory marker, creatinine, cholesterol, ketone body, cancer marker, Helicobacter pylori, step count, pulse, acceleration, position, calorie consumption, outside temperature, outside humidity, and sleep volume At least one of them is included. Vital data includes, for example, information obtained from human body fluids (eg, urine, sweat, or blood). In addition, the time-series vital data is data in which the vital data is recorded in time series.

  The vital data providing system 1 has an external system 2, an external system 3, a server 10, and a user terminal 20. The vital data providing system 1 is a system that provides time-series vital data provided from the external system 2 and the external system 3 to another device in response to a request. The other device that is the provision destination of the time-series vital data is, for example, another external system or the user terminal 20. In this example, the server 10, the external system 2, and the external system 3 are operated by different businesses. Although only two external systems and one client are shown here for simplification of the drawing, the vital data providing system 1 has three or more external systems and two or more clients. May be.

  The external system 2 is an example of a first system that collects time-series vital data of the first type from the first subject group. The external system 3 is an example of a second system that collects the second type of time-series vital data from the second subject group. The first subject group and the second subject group are subject groups each made up of a plurality of subjects, and at least some of them are different. The first type of time-series vital data and the second type of time-series vital data are one or more types of time-series vital data, and at least some of them are different. As an example, the external system 2 is a system operated by a hospital, and the time-series vital data collected by the external system 2 includes, for example, blood pressure, heartbeat, body temperature, oxygen saturation concentration (blood oxygen), and weight. . The external system 3 is a system operated by a personal health care business operator (health information management business operator), and the time-series vital data collected by the external system 3 includes, for example, blood sugar, urine sugar, and uric acid (in blood or Urine), oxalic acid, specific gravity, and protein. Besides, for example, a gym may operate an external system, and in this case, the time-series vital data collected by the external system includes, for example, the number of steps, pulse, acceleration, position, and calorie consumption.

  FIG. 2 is a diagram illustrating a functional configuration of the server 10. The server 10 includes a reception unit 101, a specification unit 102, a storage unit 103, a writing unit 104, a clustering unit 105, a reception unit 106, an extraction unit 107, and an output unit 108.

  The receiving unit 101 receives input of time-series vital data from an external system. The data received by the receiving unit 101 includes at least one of the first type time series vital data collected by the external system 2 and the second type time series vital data collected by the external system 3. The specifying unit 102 obtains, for the target time-series vital data among the time-series vital data input by the receiving unit 101, data indicating the attribute of the target subject at the time when the time-series vital data was measured. It is specified as the attribute data. The storage unit 103 stores various data. The data stored in the storage unit 103 includes, for example, a vital database 131, an attribute database 132, and a name identification database 133 (represented simply as DB131, DB132, and DB133 in the figure). The attribute database 132 stores the vital database 131. The vital database 131 is a database that records the time-series vital data that the accepting unit 101 has accepted input. The attribute database 132 is a database that records the attributes of the subject. The subject attributes are classified into those that do not change with time and those that change with time. The attributes that do not change with time are, for example, sex, date of birth, birthplace, and race. Attributes that change with time are, for example, age group, medical history, smoking history, drinking history, exercise history, living area, average sleeping time, and the like. The name identification database 133 is a database used for name identification of test subjects. The writing unit 104 writes the time-series vital data, the input of which is accepted by the accepting unit 101, to the vital database together with the information indicating the correspondence relationship with the attribute data identified by the identifying unit 102.

  FIG. 3 is a diagram showing an outline of the vital database 131. Here, the vital database 131 is represented by a matrix for convenience. One matrix shows vital data obtained from a single subject. In this example, the vital database 131 does not include so-called personal information. The personal information mentioned here is information for identifying a specific individual, and is, for example, at least one of a name, an address, a personal number (social security number), a telephone number, a mail address, and a mother's maiden name. In this matrix, each row shows a time series change of some kind of vital data. Each column shows the measured value of each vital data. Here, for simplification of description, an example in which a single measurement value is stored in each cell of the matrix will be described. In addition to the measured value of vital data, each cell includes a time stamp related to the measured value. The time stamp indicates the time when the vital data was measured or the time when the vital data was acquired. In this example, the measurement values belonging to a certain column are not necessarily the values obtained by measurement in the same time zone. For example, the heart rate in the second column is the measured value on November 28, 2018 at 9:15, while the urine sugar in the second column is the measured value on November 27, 2018 at 11:29. The matrix of FIG. 2 is recorded for each subject. In the vital database 131, each subject is distinguished by the identification number given by the vital data providing system 1, for example. The details of the vital database 131 will be described later.

  Referring back to FIG. The clustering unit 105 clusters the time-series vital data recorded in the vital database 131 based on the attribute data.

  The receiving unit 106 receives a data provision request from an external system. This provision request includes information (hereinafter referred to as “classification information”) that specifies a cluster (classification) obtained as a result of clustering by the clustering unit 105. The extraction unit 107 extracts the time-series vital data belonging to the cluster specified by the classification information from the vital database 131. The output unit 108 outputs the time-series vital data extracted by the extraction unit 107 to the device specified by the provision request. In one example, the device specified by the provision request is the device that is the source of the provision request.

  The receiving unit 106 receives a request for providing time-series vital data (hereinafter referred to as “providing request”) from another device. This provision request is transmitted from the external system 2, the external system 3, or the user terminal 20. The provision request includes information designating at least a part of the time-series vital data stored in the storage unit 103. This information includes, for example, information designating a cluster obtained by the clustering unit 105 (hereinafter referred to as “classification information”).

  In this example, the server 10 further includes an authentication unit 109 and a consideration calculation unit 110. The authentication unit 109 authenticates a request from another device such as the user terminal 20. When the authentication is successful, the extraction unit 107 extracts the data specified by the provision request from the vital database 131. The output unit 108 transmits the extracted data to the device that is the transmission source of the provision request (hereinafter referred to as “transmission source device”) or the device specified by the provision request. When the authentication has failed, the output unit 108 does not transmit the time-series vital data designated by the authentication request to the transmission source device or the like.

  The consideration calculation means 110 calculates the consideration paid for the time-series vital data accepted by the acceptance means 101. The management company of the server 10 pays the time-series vital data provision consideration to the time-series vital data provider (for example, the management company of the external system 2 and the external system 3 or each subject). The consideration calculation means 110 calculates the amount of this consideration.

  Referring back to FIG. The user terminal 20 is an information processing device for accessing at least one of the server 10, the external system 2, and the external system 3. The user terminal 20 is used by, for example, an end user. The end user is, for example, a subject. The subject means a person who provides his / her time-series vital data to the vital data providing system 1. The user terminal 20 transmits a provision request including information for identifying the own device or the subject to the external system 2, for example. The external system 2 transmits the data according to the provision request to the user terminal 20. In FIG. 1, only one user terminal 20 is comprehensively illustrated, but a plurality of user terminals 20 used by different test subjects are at least one of the server 10, the external system 2, and the external system 3, respectively. Can be accessed.

  FIG. 4 is a diagram illustrating a hardware configuration of the server 10. The server 10 is a computer device having a CPU 151, a memory 152, a storage 153, and a communication IF 154. The CPU 151 is a control device that executes a program and controls other elements of the server 10. The memory 152 is a main storage device that functions as a work area when the CPU 151 executes a program. The storage 153 is an auxiliary storage device that stores various programs and data. The communication IF 154 is an interface for communicating with other devices according to a predetermined communication standard.

  In this example, the storage 153 stores a program for causing a computer device to function as the server 10 in the vital data providing system 1 (hereinafter referred to as “server program”). While the CPU 151 is executing the server program, the CPU 151 receives the accepting unit 101, the identifying unit 102, the writing unit 104, the clustering unit 105, the receiving unit 106, the extracting unit 107, the outputting unit 108, the authenticating unit 109, and the consideration calculation. It is an example of a means 110. Further, at least one of the memory 152 and the storage 153 is an example of the storage unit 103.

  Although detailed description is omitted, the external system 2 and the external system 3 also include, for example, a general-purpose computer device having a CPU, a memory, a storage, and a communication IF. The user terminal 20 is a general-purpose computer device used by a user, such as a smartphone, a tablet terminal, or a personal computer. In the external system 2, the external system 3, and the user terminal 20, a program for causing a computer device to function as a client in the vital data providing system 1 (hereinafter referred to as “client program”) is stored. When each device executes this client program, the functions related to the processes described below are implemented. The client program executed by the external system 2 and the external system 3 (business operator) may be different from the client program executed by the user terminal 20 (subject).

2. Operation Prior to the operation description, the situation of the vital data providing system 1 will be described. In this example, a certain business operator (hereinafter referred to as “business operator A”) uses the external system 2 to provide a vital data recording service (hereinafter referred to as “service A”). The sensor used for recording vital data in the service A is, for example, a wristwatch-type so-called activity meter, which measures the number of steps and pulse of the subject. The subject wears this sensor, for example, all day long. This sensor measures the subject's step count and pulse at regular time intervals (for example, every 10 minutes), adds a time stamp to the measured value, and stores it. The subject connects the sensor to a relay device (not shown) at a desired timing and transfers vital data to the relay device. The relay device is, for example, a so-called personal computer and is connected to the Internet. The test subject is already registered in service A. The subject logs in to the service A from the relay device and uploads his / her vital data to the server 10. A user (subject) who has logged in to the service A can browse or download his / her vital data, but cannot browse or download the vital data of another person.

  A business operator different from the business operator A (hereinafter referred to as “business operator B”) provides a vital data recording service (hereinafter referred to as “service B”) using the external system 3. The sensor used for recording vital data in the external system 3 is a sensor attached to a base material such as paper and coated with an enzyme that reacts with a specific component in urine. When the urinary organ after urination is wiped with this substrate, urine reacts with the enzyme, and the sensor outputs a signal according to a specific component. The sensor has a communication device for communicating with a relay device (for example, a smartphone, not shown), and transmits a measurement value to the relay device via this communication device. The relay device that has received the measurement value adds a time stamp to the measurement value and uploads it to the server 10. A user (subject) logged in to the service B can browse or download his / her vital data, but cannot browse or download the vital data of another person.

  The service A and the service B are not compatible, the user of the service A cannot browse the vital data of the service B by using the service A, and the user of the service B uses the service B by using the vital data of the service A. Cannot be viewed.

  In this situation, a certain business operator (hereinafter referred to as "business operator C") provides a service (hereinafter referred to as "service C") that integrates these plural services. The business operator C manages the server 10. The business operator C may be the same person as either the business operator A or the business operator B.

  The operation of the vital data providing system 1 will be described based on the above assumptions. The vital data providing system 1 operates largely in two ways: (a) collecting time-series vital data from an external system, utilizing the collected time-series vital data, and (c) providing time-series vital data to a client. Be divided. The provision of time-series vital data is further divided into data provision for businesses and data provision for subjects (individuals). Each operation will be described below.

2-1. Storage of Time-Series Vital Data FIG. 5 is a sequence chart illustrating an operation according to the embodiment of the vital data providing system 1. The external system 2 and the external system 3 are in operation before the start of the process of FIG. The external system 2 and the external system 3 acquire vital data from the first subject group and the second subject group, respectively, add a time stamp to the acquired vital data, and store it as time-series vital data. It should be noted that in the following, the functional elements such as the accepting unit 101 may be described as the main body of processing, but this means that the hardware elements such as the CPU 151 cooperate with the software elements such as the server program, and other elements may be added as necessary. It means performing a process by controlling a hardware element.

  In step S101, the external system 2 transmits the time-series vital data to the server 10. The process of step S101 is triggered by a predetermined event. This event is, for example, an event that a predetermined time has elapsed since the last time-series vital data was transmitted to the server 10. Alternatively, this event is an event that the data amount of untransmitted time-series vital data exceeds a threshold value. The external system 2 stores information for specifying untransmitted time-series vital data and transmitted time-series vital data (for example, a flag indicating whether or not data divided into predetermined units has been transmitted). To do. The external system 2 refers to this information to identify unsent time-series vital data, and sends it to the server 10. When the time-series vital data is transmitted to the server 10, the external system 2 updates this information.

  In this example, the external system 2 obtains the consent of each subject in advance for providing the time-series vital data to the service C (company C). The external system 2 stores the information indicating the presence or absence of the consent in association with the time-series vital data. When transmitting the time-series vital data to the server 10, the external system 2 refers to the information indicating the presence or absence of consent, and transmits only the time-series vital data of the subject who has consented to the data provision to the server 10.

  In step S 102, the receiving unit 101 of the server 10 receives the provision (input) of the time-series vital data from the external system 2. The time-series vital data provided from the external system 2 is described in a predetermined format (hereinafter referred to as “first format”). In step S103, the writing unit 104 converts the format of the time-series vital data provided from the external system 2 from the first format to the standard format. The reference format is a standard data format (or data format) of time-series vital data, which is defined in advance in the server 10. The storage means 103 stores the first rule for converting the first format into the reference format, and the writing means 104 refers to the storage means 103 for the format of the time-series vital data accepted by the acceptance means 101. Then, the first format is converted to the standard format. The storage unit 103 converts the format of data.

  Similarly, the receiving unit 101 receives input of time-series vital data from the external system 3. The time-series vital data provided from the external system 3 is described in a predetermined format (hereinafter referred to as “second format”) different from that used in the external system 2. The storage means 103 stores the second rule for converting the second format into the reference format, and the writing means 104 refers to the storage means 103 for the format of the time-series vital data accepted by the acceptance means 101. Then, the second format is converted to the standard format.

  In step S104, the specifying unit 102 specifies target attribute data for the target time-series vital data. The target time-series vital data refers to the target time-series vital data of the time-series vital data (group) that the receiving unit 101 has received input. The target subject means a subject of the target time-series vital data. The target attribute data is data indicating the attributes of the target subject at the time when the time-series vital data was measured. The identifying unit 102 writes the attribute data corresponding to the target time-series vital data in the attribute database 132. In the attribute database 132, the attribute data is recorded in a format in which the time change of the attribute can be referenced.

  Various methods are used to specify the target attribute data. In one example, the external system 2 transmits the time-series vital data and the attribute data as a set to the server 10. The external system 2 makes the subject a direct member and can acquire the attributes of the subject. When the time-series vital data and the attribute data are received as a set, the specifying unit 102 specifies the attribute data received as a set with the target time-series vital data as the target attribute data. In another example, when the target time-series vital data is received alone (not as a set with the attribute data), the identifying unit 102 determines that the previous attribute is maintained, and at that time, the attribute database 132. It is determined that the attribute indicated by the latest attribute data registered in is maintained. Specifically, when the receiving unit 101 receives time-series vital data from 00:00 to 23:59 on December 3, 2018, there is no attribute data that is set with the target time-series vital data. At this time, the identifying unit 102 determines that the attribute indicated by the latest attribute data of the subject recorded in the attribute database 132 (for example, the attribute at 23:59 on December 2, 2018) is the target time-series vital data. It is determined that the period (00:00 to 23:59 on December 3, 2018) will be maintained. In yet another example, the target time-series vital data or attribute database 132 includes a link indicating a resource (location on the network) that stores the attribute data. The identifying unit 102 acquires the attribute data from the resource indicated by this link.

  The time-series vital data transmitted from the external system 2 may include information designating a method of identifying attribute data (for example, any one of the above three examples). The specifying unit 102 specifies the attribute data by using the method specified by this information. Alternatively, the order of priority is given in advance to the plurality of specifying methods, and the specifying unit 102 tries in order from the specifying method with the highest priority, and if the attribute data is successfully specified by a certain method, the specifying unit 102 proceeds to the next process.

  Further, the writing unit 104 writes the time-series vital data converted into the standard format in the vital database 131 (step S105). At this time, the writing unit 104 writes, in addition to the time-series vital data, information indicating the correspondence relationship with the attribute data specified in step S104 in the vital database 131. The information indicating the correspondence with the attribute data includes, for example, at least one of information indicating the location of the attribute data, identification information of the attribute data, and the attribute data itself. In this case, the writing unit 104 may write the time-series vital data and the attribute data in the vital database 131 and the attribute database 132 in a data structure that shows the correspondence on the time axis.

  When writing the time-series vital data to the vital database 131, the writing unit 104 converts (or adds) the identification information of the subject. The time-series vital data includes identification information for identifying the subject (user) from whom the vital data was acquired. Here, in the external system 2 and the external system 3, each subject is assigned unique identification information (member number, etc .; hereinafter referred to as “individual identification information”), and the same person is assigned to the external system 2 and the external system 3. When both are used, the identity of the subject may not be specified only by the identification information given by the external system 2 and the external system 3. The conversion of identification information is performed to deal with this problem, and is a process corresponding to so-called name identification. The name identification database 133 is used for this processing.

  FIG. 6 is a diagram illustrating the name identification database 133. In the name identification database 133, the identification information in the external system 2, the identification information in the external system 3, and the identification information in the server 10 are associated with each other. In the example of FIG. 5, common identification information (hereinafter referred to as “common identification information”) is given to the subject to whom the identification information “ABC001” is given in the external system 2 and the identification information “123456” is given in the external system 3. “966754B” is given by the server 10. Further, the same subject as the subject to which the identification information “DEF209” is given in the external system 2 is not registered in the external system 3 (denoted as “NA” in the figure), and is used as common identification information for this subject. "823467C" is given. The name identification database 133 is created and updated by the operator operating the server 10, using the subject lists provided by the operators A and B. Alternatively, when the name identification database 133 receives unknown identification information from the external system 2, the name identification database 133 may make an inquiry to the external system 2 about personal information corresponding to the identification information. In response to this inquiry, the external system 2 transmits a predetermined number of items of personal information (for example, telephone number and date of birth) of the personal information corresponding to the identification information to the server 10. The server 10 stores a database (not shown) that associates the identification information of the subject with a part of the personal information, and refers to this database to identify the identification information corresponding to the received personal information. In this example, the writing unit 104 is an example of a conversion unit that converts the individual identification information into the common identification information.

  Referring back to FIG. When the writing of the time-series vital data to the vital database 131 is completed, the consideration calculation means 110 performs a consideration calculation process (step S106). That is, the consideration calculation means 110 calculates the amount of consideration for providing the time-series vital data, which is provided to the external system 2. The operating enterprise of the server 10 calculated here pays the operating enterprise of the external system 2 the consideration for providing the time-series vital data.

The consideration is calculated, for example, as follows. In one example, the consideration is calculated using the number of subjects, the number of measurement points, and an index indicating the quality of data (hereinafter referred to as “quality index”) (the simplest example is the product of these). The index showing the quality of data is obtained as follows, for example. In this example, for time-series vital data, a plurality of constraint conditions on the time axis that the time-series vital data should satisfy are set. These constraints are conditions regarding the quality of time-series vital data. The consideration calculation means 110 calculates, for example, the quality index in accordance with the proportion of these constraints. In one example, this constraint is, for example:
(A) The time from the time of the first measurement point (for each subject) to the time of the last measurement point is equal to or longer than the threshold time. This threshold time is determined, for example, according to the cycle of transmitting time-series vital data from the external system to the server 10. As an example, this threshold time is half the period. For example, when the cycle is 24 hours, the threshold time is 12 hours.
(B) The time interval between two adjacent measurement points (for each subject) is less than or equal to the threshold time. This threshold time may also be determined according to the cycle of transmitting time-series vital data from the external system to the server 10 as in (a). The threshold time of (b) is shorter than the threshold time of (a).
(C) The number of measurement points per unit time is greater than or equal to the threshold value.
The above threshold time and threshold may be set in a plurality of levels. For example, with respect to the condition (a), the threshold time may be set in 6 stages of 2 hours, 6 hours, 12 hours, 24 hours, 48 hours, and 96 hours (the data quality is higher later). . Further, with respect to the condition (b), the threshold time may be set to 5 stages of 4 hours, 2 hours, 60 minutes, 30 minutes, and 5 minutes (the data quality is higher in the latter time). Furthermore, these thresholds may be changed according to the type of vital data.

  Regarding the condition (a), for example, when time-series vital data of 100 subjects are provided, 40 of them satisfy the condition (a), and 60 of the remaining time-series vital data satisfy the condition (a). When (a) is not satisfied, a quality index corresponding to a ratio of 40% that satisfies the constraint condition is calculated.

  Regarding the condition (b), for example, in time-series vital data consisting of 101 measurement points obtained from a certain subject, 56 sections out of the sections between 100 adjacent measurement points satisfy the condition (b), and the remaining 44 sections. Does not satisfy the condition (b), the ratio that the constraint condition is satisfied for this test subject is 56%. When the average of all the subjects is 55% in the condition that the constraint is satisfied, a quality index corresponding to the ratio 55% in which the constraint is satisfied is calculated. When taking an average for all test subjects, weighting may be performed according to the number of measurement points or the like.

  The consideration calculation means 110 stores the consideration calculated as described above in the storage means 103 together with information specifying the time-series vital data to be the object of the consideration. The operating company of the server 10 pays the consideration to the operating company of the external system 2 based on this record.

  In this way, the time-series vital data from the external system 2 is recorded in the vital database 131. Although detailed description is omitted, the reception of time-series vital data from the external system 3 is similar to that of the external system 2. However, the event that triggers the transmission of the time-series vital data to the server 10 and its frequency may be different between the external system 2 and the external system 3.

  Further, here, the example in which the time-series vital data is provided from the external system 2 or the external system 3 to the server 10 has been described, but the time-series vital data may be directly transmitted from the user terminal 20 to the server 10. . In this case, as described in the example of the external system, authentication using time-series vital data as an authentication key may be performed.

2-2. Analysis of Time-series Vital Data The clustering means 105 analyzes the time-series vital data recorded in the vital database 131. This analysis includes clustering processing of time-series vital data.

  The clustering means 105 analyzes the relevance between the subject's attribute and the time-series vital data. A technique such as so-called AI, machine learning, or deep learning may be used for analyzing the data. In one example, the clustering unit 105 clusters the time-series vital data (classifies into a plurality of clusters). In this case, the clustering unit 105 is an example of a clustering unit. At the time of clustering, the time-series vital data of each subject may be used as it is, or the statistical value (average value, maximum value, minimum value, or the like) of the time-series vital data of each subject may be used. In one example, clustering is performed for each type of time-series vital data (for example, clustering is performed separately for uric acid and oxalic acid). Further, the clustering unit 105 may perform clustering on a certain type of time-series vital data. At this time, the clustering unit 105 may add the result of the clustering in a format that can be referred to in other types of time-series vital data. In one example, the clustering unit 105 stores the information indicating the classification based on the result of the clustering in the vital database 131 in association with the identification information of the subject. Alternatively, the clustering unit 105 may cluster the attributes of the subjects.

  Further, the clustering unit 105 may analyze which attribute affects the specific time-series vital data. More specifically, the clustering unit 105 analyzes the correlation between the lung cancer marker and the smoking history, and analyzes the correlation between the exercise history and the urine sugar. In this way, the clustering unit 105 can obtain information indicating the relationship between the vital data and the subject attribute from the accumulated time-series vital data. The clustering unit 105 can further identify a subject having an attribute that is likely to be affected by a specific disease from this information.

  In another example, the clustering unit 105 compares the time-series vital data of a particular subject with the time-series vital data of another group of subjects having the same or corresponding attributes as the subject, and determines that particular subject. Anomalies in the time-series vital data may be detected. For example, the clustering unit 105 can detect an event in which the uric acid value of a subject is significantly higher than the uric acid values of other subjects of the same age group and the same sex.

  In still another example, the clustering unit 105 may detect an abnormal change or its sign from the time change of the measurement value in the time-series vital data of a specific subject. For example, when the oxalic acid measurement value of a certain subject has been around 10 for the last two years, but suddenly rises to about 40, the clustering means 105 causes an abnormal change or its sign. To detect.

  The clustering unit 105 records the information obtained by any of the above-described analyzes in the vital database 131 or another database. Further, the clustering unit 105 may output this information to another device in response to a request or spontaneously. The output destination of this information is, for example, the external system 2, the external system 3, the user terminal 20, or another device.

2-3. Provision of time-series vital data 2-3-1. For External System FIG. 7 is a sequence chart illustrating an operation related to provision of time-series vital data for an external system. Here, an example will be described in which the external system 2 acquires time-series vital data of one or more subjects including subjects other than the user of the external system 2. The external system 2 acquires these time series vital data in order to provide the statistical value of the time series vital data to the user of the external system 2, for example.

  In step S201, the external system 2 transmits a login request to the server 10. The login request includes, for example, the identification information (contract ID etc.) of the external system 2 and the authentication key. The authentication key is, for example, a password. The identification information and the password of the external system 2 are given by, for example, the operator of the server 10. Upon receiving the login request, the authentication means 109 of the server 10 authenticates whether the combination of the identification information and the authentication key included in the login request is valid (step S202).

  In another example, the authentication key includes at least a part of the time-series vital data that the external system 2 has obtained from the subject in the past. This time-series vital data is a part of the time-series vital data already transmitted to the server 10 (recorded in the vital database 131). The authentication means 109 of the server 10 collates the time-series vital data included in the received authentication key with the data in the vital database 131. When it is determined in this collation that the same data is recorded, the authentication means 109 authenticates this login request. If it is determined that the same data is not recorded, the authentication means 109 does not authenticate this login request. Hereinafter, this technique will be described in more detail.

FIG. 8: is a figure which illustrates the time series vital data of a certain subject. The horizontal axis of this figure shows the measurement time, and the vertical axis shows the measured value (oxalic acid in this example). As described with reference to FIG. 3, the time-series vital data has a set of a measurement value and a time stamp as a unit. Since the measurement of vital data is performed at an arbitrary timing, the arrangement of the set of measurement values and time stamps is unique to the subject. For example, if you look at a certain number of data (eg 3 sets) from a certain reference time (eg current time) (the part surrounded by the broken line in the figure), the set of (measurement value, time stamp) is
(20.1, 2018/11/27 07:56)
(25.9, 2018/11/27 11:29)
(22.2, 2018/11/27 18:52)
An array of the above three sets of data is obtained. The array of these three sets of data is highly likely to be unique to the subject. The probability increases as the number of acquired data sets increases. Furthermore, the sequence (20.1, 25.9, 22.2) obtained by extracting only the measured values from the above example is also highly likely to be unique to the subject. Alternatively, the sequence obtained by extracting only the time stamp from the above example is also likely to be unique to the subject. Therefore, a part of the time-series vital data can be used as the authentication key. Here, "a part of the time-series vital data" means a part of the set of measured values and time stamps (first example), and a part of only one of the measured values and time stamps ( This is a concept that includes both the second and third examples).

  According to this method, the greater the number of measurement points, the higher the probability that the data array is unique, that is, the stronger the security. However, when the number of measurement points is small, such as in the initial stage when the time-series vital data is taken, there is a problem that security is inevitably weakened. In order to deal with this problem, in the example in which part of the time-series vital data is used as the authentication key, this “part” may be switched according to some trigger. The switching trigger is, for example, a time zone of access or required security strength. The target of switching is the number of subjects, the type of vital data, or the content of the data set. For example, if the number of measurement points of the time-series vital data used for the authentication key is smaller than the threshold value, a set of measurement values and time stamps is used as the authentication key, and if the number of measurement points is greater than or equal to the threshold value. Only one of the measured value and the time stamp may be used as the authentication key. Alternatively, if the number of measurement points is smaller than the threshold value, multiple types of vital data (for example, uric acid and oxalic acid) are used as authentication keys, and if the number of measurement points exceeds the threshold value, fewer types of vital data are used. (For example, only uric acid) may be used as the authentication key.

  According to this example, the authentication key is updated frequently (every time when new time-series vital data is input), so that the security can be strengthened.

  Referring back to FIG. In step S203, the server 10 transmits the result of the process for the login request (authentication success or authentication failure) to the external system 2 which is the transmission source of the login request. When the notification of successful authentication is received, the external system 2 transmits a time-series vital data providing request to the server 10 (step S204). This provision request is information for narrowing down the time-series vital data, for example, the type of vital data (eg uric acid and urine sugar), the subject's attributes (eg male in his 40s), time zone (eg 2017-2018). Information for identifying at least a part of the provider of the vital data (example: service A) and the analysis result by the clustering means 105 (example: cluster with many lung cancer patients) (the aforementioned classification information). )including.

  In step S205, the extraction unit 107 of the server 10 extracts the data narrowed down by the information included in the provision request from the vital database 131. In this example, the data to be extracted is not only the time-series vital data provided by the external system 2 but also the time-series vital data provided by all the systems including the external system 3 (the time-series of all subject groups). Vital data). The output unit 108 transmits the extracted data to the external system 2 that is the transmission source of the provision request (step S206). The consideration calculation means 110 calculates the consideration of the time-series vital data transmitted to the external system 2. The consideration is calculated, for example, in the same manner as the method described in step S106 (the index used may be different from that used when data is input). Alternatively, the business operator C (the operator of the server 10) may charge the time-series vital data according to the contract with the business operator A (the operator of the external system 2). This contract may be, for example, a flat-rate contract or a pay-as-you-go contract.

  The business operator C may set a limit on the time-series vital data that can be provided to the business operator A by contracting with the business operator A. The restrictions are related to the source of vital data (eg, only the data of service A and service B can be provided), the time of measurement (eg, only data measured in 2018 can be provided), and the attribute of the subject. It may include at least one of the ones (for example, only data of 40s can be provided, only data of residents in the Tohoku region can be provided). In this case, the server 10 stores information regarding the contract with the business operator A in the storage unit 103. The extraction means 107 extracts only the data that matches the restriction indicated by this information.

  The data extracted by the extraction unit 107 may include information indicating the analysis result by the clustering unit 105 (for example, information indicating the classification of clustering).

2-3-2. For subjects The operations related to providing time-series vital data for subjects are basically the same as those for businesses. Particularly, in this example, when the user's vital data is used as the authentication key, there is an advantage that the subject (user) does not need to remember the password. However, when the provision request is transmitted from the user terminal 20 to the server 10, the provision request includes identification information for identifying the user (subject). This identification information may be either identification information for individual services (service A or service B) or common identification information. The extraction unit 107 extracts vital data of the subject identified by the identification information included in the provision request from the vital database 131. The provision request may include information for narrowing down vital data (eg, uric acid data in 2018) in addition to the identification information of the subject. The extraction means 107 extracts the vital data narrowed down by this information from the vital database 131. At this time, the extraction unit 107 may also extract information indicating the analysis result by the clustering unit 105. The output unit 108 transmits the extracted data to the user terminal 20 that is the transmission source of the provision request.

  FIG. 9 is a diagram illustrating a screen displayed on the user terminal 20. This example shows changes in the uric acid level of a subject. In this example, the clustering means 105 has found that signs of gout are seen at the two most recent measurement points, and a message 91 indicating the result is displayed. Specifically, the message "There are signs of gout. We recommend that you visit us." Is displayed. Further, a link "(Search for affiliated hospital)" is displayed below this message. When the user selects this link, the screen of the user terminal 20 switches to a screen for searching for a partner hospital of the vital data providing system 1. The affiliated hospital here is an example of a management body of the external system. From this screen, the user searches for a hospital near his / her home or work, for example. When the user selects one hospital from the searched hospitals, the screen of the user terminal 20 may be switched to a screen for reserving a medical examination at the selected hospital. When the medical examination is reserved, the server 10 may transmit the time-series vital data of this subject to the reserved hospital. As described above, according to the present embodiment, it is possible to detect signs of illness earlier, and also in subsequent medical examinations, the vital data before the medical examination is automatically transmitted to the hospital, and the doctor determines the condition of the subject. You can know in more detail.

  In another example, the vital data providing system 1 may recommend exercise in a sports club. In this case, a sports club search screen is displayed instead of the hospital search screen. A sports club is also an example of an external system management entity. In yet another example, the vital data providing system 1 may recommend the purchase of health foods or supplements. In this case, a link to a mail order site for health foods or supplements is displayed instead of the search screen for the hospital or sports club. As described above, according to this embodiment, various information can be provided to the subject according to the vital data of the subject.

3. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made. Hereinafter, some modified examples will be described. Two or more of the following modifications may be used in combination.

  Some of the functions described as being implemented in the server 10 in the embodiment may be implemented in the client device (external system 2, external system 3, or user terminal 20). For example, the external system 2, the external system 3, or the user terminal 20 may transmit the time-series vital data to the server 10 after converting the identification information unique to each service into common identification information.

  Some of the functions described as being implemented in the server 10 in the embodiment may be implemented in another server device. For example, the clustering unit 105 may be mounted on a server device different from the server 10.

  The method by which the specifying unit 102 specifies the attribute data is not limited to the one exemplified in the embodiment. For example, the server 10 may include an estimation unit (not shown) for estimating the attribute data of the subject. If the subject's attribute data cannot be found even by a predetermined method, this estimating means estimates the subject's attribute. In one example, the estimation unit estimates the present attribute of the subject from the past attribute data of the same subject. At this time, the estimating means may estimate the attribute data by referring to the time change of the vital data correlated with the attribute data. In another example, the estimation unit may estimate the attribute of the target subject from the attribute data of other subjects belonging to the same cluster as the target subject in the analysis result of the clustering unit 105. In this case, clustering is performed based on a certain type of time-series vital data.

  The attribute data is not limited to the one exemplified in the embodiment. For example, part of the data acquired as time-series vital data may be used as attribute data for another type of time-series vital data.

  When using a part of the time-series vital data as an authentication key for access to the server 10, information (index information) for identifying a “part” used as the authentication key from the time-series vital data group is provided. You may transmit to the server 10 from the transmission source apparatus of a request. The index information may include, for example, subject identification information that identifies one subject from a plurality of subjects. Alternatively, the index information may include time zone information that specifies the time zone in which the time-series vital data was measured. According to this example, the range in which the server 10 searches the vital database 131 can be narrowed down, and the load can be reduced.

  The business A, the business B, or the business C may give a privilege to the vital data provider. In this case, each business operator may change the privilege according to the quality of the provided data. That is, a high privilege may be given to a subject who has provided high-quality data. The data quality is evaluated based on, for example, the same method as the quality index in step S106.

  When providing vital data in accordance with a providing request from the user terminal 20, the extracting unit 107 may thin out the measurement points according to the time length of the vital data to be provided. For example, when vital data for 10 years is requested, the extraction unit 107 thins out the number of data points in a unit period to 1/10 as compared with the case where data for 1 year is requested.

  The sequence chart in the embodiment is merely an example, and the operation of the vital data providing system 1 is not limited to this. For example, the order of processing may be changed from that described in the embodiment.

  In the embodiment, the programs executed by various computer devices may be provided in a state of being recorded in a non-transitory storage medium (CD-ROM, flash memory, etc.).

For the target time-series vital data among the time-series vital data that the input has been accepted, at the time when the time-series vital data was measured, a step of identifying attribute data indicating the attributes of the target subject.
Writing the time-series vital data for which the input has been accepted into a vital database together with information indicating a correspondence relationship with the identified attribute data;
Clustering the time-series vital data recorded in the vital database based on the attribute data,
Receiving a data provision request from another device, the request including provision of classification information specifying classification by the clustering;
From the vital database, extracting the time-series vital data belonging to the cluster specified by the classification information,
A step of outputting the extracted time-series vital data to a device specified by the provision request,
The provision request includes an authentication key for authenticating the other device,
The program causes the computer to execute a step of authenticating the device using an authentication key included in the provision request,
When the other device is authenticated in the authenticating step, in the outputting step, the time-series vital data selected according to the providing request is output,
The authentication key includes at least one of a time stamp and a measurement value of at least two data points among the time-series vital data acquired in the past in the device,
In the step of authenticating, the authentication key is authenticated by collating with the time-series vital data stored in the vital database.
